Abstract: In an image processing apparatus, a processor reads a boot loader from a first storage device, reads a main program from a second storage device by executing the boot loader, and, by executing the main program, transitions to an operation state. The first storage device is mounted on a board on which the processor is mounted. The second storage device is electrically connected with the processor via a bus. When an error occurs during reading of the main program from the second storage device, the processor automatically reads a backup program from the third storage device and displays a screen including warning information on a display device by executing the backup program.

Abstract: When performing a specific process accompanied with reading or writing a storage unit in a sleep mode, the power supply control unit control a control unit and the storage unit to temporarily return. When detecting movement in a period from start to end of the temporary return, the power supply control unit restarts power supply to a display panel. The control unit controls to display warning informing that the storage unit is working and urging to be careful so that the power is not disconnected.

Abstract: A shelf unit assembled by joining a vertical member as a stud to a corner of a shelf or a chest, wherein the shelf unit is assembled with a shelf or chest in which the surface of the corner is formed into a corrugated surface of forming corrugation in a right-to-left direction, and a vertical member in which the surface of a portion to be joined with the corner is formed into a corrugated surface that overlaps the corrugated surface of the corner, whereby the shelf unit can be maintained always in a stable state without jolting of the vertical member or slack of the screw to facilitate assembling operation and reduce the cost.
